Abstract

Compounds, compositions, and methods for modulation of Hec1/Nek2 interaction are provided. Especially preferred compounds disrupt Nek2/Hec1 binding and are therefore useful as chemotherapeutic agent for neoplastic diseases.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A method of treating a neoplastic disease, comprising:
 administering to a mammal in need thereof a pharmaceutical composition comprising a compound having a structure according to Formula I 
 
       
         
           
           
               
               
           
         
         R 1  is alkyl, OR a , SR a , or —S(O) 2 R a ; 
         R a  is alkyl, or aryl substituted with alkoxy; 
         R 2  and R 3  are independently alkyl; 
         R 4  is hydrogen; 
         R 5  is pyridyl optionally substituted with alkyl, fluoroalkyl, halogen, or alkoxy; 
         wherein the compound is present in the composition an amount effective to disrupt Hec1/Nek2 binding in the mammal when the composition is administered to the mannal; and 
         wherein the neoplastic disease is selected from the group consisting of breast cancer, prostate cancer, cervical cancer and leukemia. 
       
     
     
       2. The method of  claim 1  wherein R 1  is SRa, ORa, or, —S(O)2Ra, and wherein Ra is aryl substituted with alkoxy. 
     
     
       3. The method of  claim 1 , wherein the compound has a structure selected from the group consisting of 
       
         
           
           
               
               
           
         
         
           
           
               
               
           
         
       
     
     
       4. The method of  claim 1  wherein the compound has the structure 
       
         
           
           
               
               
           
         
       
     
     
       5. The method of  claim 1  wherein the compound has the structure 
       
         
           
           
               
               
           
         
       
     
     
       6. The method of  claim 1  wherein the compound has the structure 
       
         
           
           
               
               
           
         
       
     
     
       7. The method of  claim 1  wherein the compound has the structure 
       
         
           
           
               
               
           
         
       
     
     
       8. The method of  claim 1  wherein the compound has the structure 
       
         
           
           
               
               
           
         
       
     
     
       9. The method of  claim 1  wherein the compound has the structure 
       
         
           
           
               
               
           
         
       
     
     
       10. The method of  claim 1  wherein the compound has the structure 
       
         
           
           
               
               
           
         
       
     
     
       11. The method of  claim 1  wherein the compound has the structure 
       
         
           
           
               
               
           
         
       
     
     
       12. The method of  claim 1  wherein the pharmaceutical composition is formulated for injection or oral administration. 
     
     
       13. The method of  claim 1  wherein administration of the pharmaceutical composition also triggers Nek2 degradation. 
     
     
       14. The method of  claim 1  wherein the compound has an antiproliferative effect on tumor cells with an IC50 of less than 1 microM. 
     
     
       15. The method of  claim 1 , wherein the compound has the structure
